DOSAGE BOTTLE.

Application filed February 1, 1922.

T 0 all whom it may concern Be it known that I, VILLIATA'I J. Covi-JLL, a citizen of the United States, residing in the city and county of San Francisco and State of California, have invented a new and useful Improvement in a Dosage Bottle, of which the following is a specification.

My invention relates to dosage bottles and the like wherein a slidably mounted piston is arranged within acontainer to dispense variable and predetermined quantities of liquid therefrom by variations in pressure within the container.

The primary object of my invention is to provide an improved dosage bottle.

Another object of my invention is to provide an improved bottle adapted to dispense varied quantities of liquid therefrom without removing the cork and without use of an auxiliary measuring means.

A further object is to provide an improved container having a dispensing tip adapted to prevent liquid dispensed therethrough from clinging to the sides of the container, and which may be utilized as a syringe if desired.

A further object is to provide a device adaptable for either a dosage bottle or syringe which is readily refillable.

A further object is to provide an improved device which may be conveniently carried upon the person or in the luggage of a user without danger of spilling the contents, or which may be stood on end upon any suitable surface after the fashion of an ordinary bottle.

A still further object is to provide a dosage bottle of the character described which may be manufactured at a relatively low cost.

I accomplish these and other objects by means of the device disclosed in the drawings forming a part of the present specification wherein like characters of reference are used to designate similar parts throughout said specification and drawings, and in which: i

but is equally useful in the sickroom or other 1 place to facilitate the dispensing of'a measured quantity of medicine to be administered. The dispensing tip may be used as a nozzle to adapt the bottle for use as a syringe, or the container may be modified by omitting the supporting lugs shown in Figs. 1 and 2 and obtain a device primarily useful for a syringe as shown in 3 and 4.

Referring to the drawings, the numeral 1 is used to designate a container having a neck portion 2 at thetop thereof and a dispensing tip 3 having a dispensing aperture 4 therethrough in the bottom of the con- 'tainer in alignment with the neck 2. A; tu-

bular member 6 is mounted within the neck portion 2 and arranged to extend inwardly into the upper portion of the container 1 in alignment with the tip-3. The member 6 is preferably provided with a flange 7 at the top thereof to extend over the neck portion, a suitable packing 8 of rubber, cork, or other suitable material being provided between the sides and flange of the member 6 and the neck 2 to give an air tight fit. A cap 9 is threaded onto the neck 2 and arranged to bear against the flange 7 to normally hold the member 6 in position.

A stem 11 is slidably mounted within the member 6, the inner end of the stem extending inwardly from the member 6 and'being providedwith a tip 12 of soft rubber or other resilient material adapted to fit into the tip 8 to normally close the aperture 4 therein. A piston 13 formed from rubber, cork, or other suitable material adapted to form an air tight fit with the member 6 is secured upon the stem 11 within the member 6, said piston being arranged to normally occupy a position adjacent the inner end of the tubular member 6. The stem is most readily made from glass rod, the glass being heated and upset to form enlarged portions i l and 16 to hold the tip 12 and the piston 13 in place.

The outer end of the stem 11 extends outwardly through an aperture in the cap 9 and has a ring 17 or other element adapted to be gripped by an operator secured thereto whereby the stem and piston may be moved to dispense a liquid with which the container is filled.

Liquid is dispensed from the container in the following manner: The stem is moved outwardly from the container 1 by the ring 17, thereby receding the piston 13 from its normal position at the inner end of the memher 6, and moving the tip 12 out of contact with the dispensing tip 3. The receding of the piston creates a partial vacuum within the container, said Vacuum causing air to be drawn in through the dispensing aperture 4, to restore atmospheric pressure within the container. The piston 13 is now returned to its normal position within the member 6 by pushing the stemv l1 inwardly, the inward movement of the piston operating' to increase the pressure within the con tainer and thereby force a portion of the contents outwardly through the dispensing aperture l.

The amount of liquid displaced from the container will be dependent upon the dis tance moved by the piston 13, the amount being approximately equal to the volume displaced by the piston in moving from its receded to normal positions, the variation being due to the compression of the air within the container. To facilitate the dispensing of a measured quantity of liquid from the container, 1 have provided a plurality of calibrations 18 indicating any desired units of measurement as for instance a number of drops, or fractional parts of a teaspoon, or in cubic centimeters or other suitable unitsv In this manner any desired measure of liquid may be dispensed without recourse to anv external measuring device such as a spoon or a graduated container. When a medicine is to be administered in doses of a fixed amount, the stem may be withdrawn to the corresponding calibration and the desired quantity of liquid dispensed into a glass of water or into any desired receptacle as above described without removing the cork. The return of the tip 12- into its normal position at each operation insures against leakage from the container, and the extended tip l insures that the liquid dispensed will drop freely from the container without clinging to the bottom thereof.

By slightly increasing the size of the tip portion 3 the container may be utilized as a syringe after the usual fashion. The tip is protected from breakage by lugs 19 formed inaenea upon opposite sides of the tip upon the bottom of the container to prevent the inadvertent striking of the tip by or upon an outside body. The lugs are squared upon their bottoms to form legs upon which the container may be stood as with the ordinary bottle.

The body may be made of any desired size or shape according to the use to which it is to be placed, the form shown being only one exemplification of the many shapes that might be used; However, as the device is particularly useful for travelers and the like, a compact flattened design such as shown affords greatest convenience for carrying upon the person or within the luggage of a user.

In the modified form of the invention shown in Figs. 3 and 4 of the drawings, the supporting lugs 19 are omitted thereby facilitating the use of the device as a syringe. In this connection the device is operated as a syringe in the usual manner, the dispensing of a liquid depending, as above described, upon the relative degrees of vacuum and pressure formed within the container when the piston is receded and advanced within the member 6. It will be readily seen from the drawing that the construction of the device is materially simplified, the container 1 being easily blown from glass and the single tubular member and the piston stem being readily fitted and assembled therewith. As a syringe the size and bulk of the container may be reduced and accommodated for carriage in the pocket of a user.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is:
